If you are encrypted no need to flash DFE.
Yes flash it in TWRP and it's done.
You need to have adb or minimal adb and fastboot (run cmd as admin). Follow these steps.
This worked for me! Thank you!You need to have adb or minimal adb and fastboot (run cmd as admin). Follow these steps.
If your PC doesn't recognize your device in fastboot mode you may also need amd/intel fastboot fix which you can find it also in my guide.
A different way to apply the update is by flashing twrp by reignz NSE version and use that twrp and simply flash the zip.
If you are not happy with stock kernel you can try NGK with NGK App and choose battery profile (you need to be rooted to use NGK app) but even without ngk app battery should be fine.
Tried migrating from the latest Lineage to PixelExperience_Plus_beryllium-12.1-20220817-0755-OFFICIAL.zip, and nothing I tried (& nothing written here) worked.
Tried with twrp-3.6.2_9-0-beryllium.img and twrp-beryllium-v3.6.2-A12-NSE-V4.img and every time i ended up with "No OS installed" when rebooting & rescue party booting into TWRP. When i just tried the instructions on the first comment (which are APPARENTLY wrong) it even kept Lineage's recovery installed so the zip may not be installing anything anywhere
EDIT: i think i got it working?? if this also happens to you get a non-NSE recovery and wipe system_ext as well
